OIL-BURNER.

To all whom it may concern Be it known that I, GFEORGE Josuri-r BoLnUo, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented a new and useful Oil-Burner, of which the following is a specification. I

My invention relates to improvements in that class of oil burners which are adapted to burn oil as a fuel in connection with furnaces, stoves and steam boilers; and the object of my invention is to provide an oil burner which may be e'llicient, reliable, durable, simple in construction and comparatively inexpensive to manufacture. I attain this object by a burner constructed of any suitable metal, preferably of cast iron, in accordance with theplan shown in the accompanying diagrammatical drawings which illustrate the essential features of my invention as applied to a heating stove and in which Figure 1 is a view in sectional elevation of my invention on broken line g -g of Fig. 2. A cross-sectional plan view of part of same is shown in Fig. 2 looking downward from broken line e-z of Fig. 1. Fig. 3 is a perspective view of a detail of my invention while Fig. 4 is a perspective view of essential parts thereof.

Like reference numbers indicate like parts throughout the drawings.

Referring to Fig. 1 of drawings, 9 represents a fragment of the casing of a stove from which a suitable stove pipe, not shown, may conduct products of combustion. A burner is disposed on the floor of and within the stove casing 9 which consists of a rectangular formed base 14 provided with a raised ridge 21 and with an upwardly projecting hollow square 15 which resembles a square box without a cover.

This hollow square 15 is provided with a hole disposed in the center of its bottom adapted to receive an oil supply pipe 17 through which oil may find passage into the burner.

Fig. 3 shows a square plug 16 provided with a projection 18 on each of its vertical sides near its top, and on its bottom it is provided with two grooves 19 which cross from one side to the other at a right-angle to each other. This plug 16 is of a size and shape that will adapt it to be disposed Specification of Letters Patent.

Serial No. 635,694.

bottom thereof while the projections 18 engage with the inner sides of the walls of said hollow square 15 whereby a narrow space is provided between said walls and the sides of the plug 16, as indicated in Figs. 1 and 2. \Vhen the plug 16 is placed within the hollow square 15 and is resting 011 the bottom thereof the grooves 19 serve as oil ducts through which oil may flow from the pipe 17 into the space between the walls of the square 15 and the sides of the plug 16. Around and outside of the base of the walls of the hollow square 15 and at a short distance therefrom is a raised ridge 21. which forms a sort of gutter 20 that may serve to catch any oil overflowing the top of the hollow square 16.

In operation, of my invention, oil from some suitable source is caused to flow upwardly through oil pipe 17 to grooves 19 through which grooves 19 the oil reaches the space between the hollow square 15 and the sides of plug 16 until such oil overflows the walls of the hollow square 15 into the gutter 20. When the gutter 20 has a suitable quantity of oil in it the How of oil through pipe 17 is shut off and the oil in the gutter 20 is ignited. Air for purposes of combustion enters through two holes 22 in the bottom of stove casing, as shown in Fig. 1, thence upwardly into a chamber 23 as indicated by arrows, (which chamber 23 is formed by an inelosing case or cover whose outward form is clearly shown in perspective in Fig. 1) thence over the top of partitions 24, thence downwardly and outwardly through holes 25 disposed one on each side of the walls of the inclosing cover which holes 25 are indicated in Fig. 4 and which holes 25 form the point of combustion wherefrom-the flame and products of combustion may flow upwardly through stove casing 9 to a stove pipe not shown. When the temperature of the plug 16 and other portions of the burner is sufficiently high by reason of burning of the oil in the gutter 20 then oil is again admitted to the burner through pipe 17 at a proper rate of flow to maintain the desired heating efii'ect. Manifestly the high temperature of the plug 16 and the walls of the hollow square 15 will act rapidly to heat the oil as it passes through the narrow space between the plug 16 and walls of the square 15 and within the hollow square 15 to rest on the thus by continued operation all oil to be consumed reaches the point of combustion at a very high temperature it not actually in the form of gas.

Obviously parts of my invention which I have shown as of rectangular or square form might be made of circular or other form without departing from the spirit of my invention.

It will be observed that the plug 16 readily may be withdrawn from the hollow square 15 for the purpose of cleaning the burner and further by reason of the solidity and mass of said plug 16 it will be durable for long continued use at a comparatively high temperature.

Having described the essential features of my invention what I claim is:

In a burner of the class described, a floor-bottom provided with a hole in its central portion through which oil may flow toward a point of combustion, vertical walls disposed about said hole and fixed upon said floor-bottom, a solid plug of metal removably disposed within said walls to rest upon and be supported by said floor-bottom, said plug being of a size to aiford suitable space for flow of oil between its sides and said walls, oil-grooves formed on the' bottom of said plug to extend radially from the center of said bottom to the vertical sides of said plug, two oblong holes which form openings through said fioorbottom and which are disposed one on each of two opposite sides of said walls, and a removable, oblong and box-like casing adapted to rest upon said floor-bottom and cover said walls, said plug and said two oblong holes, said casing being provided on each of its two largest sides with an opening through which a flame and products of combustion may pass and further provided with suitable deflecting partitions disposed to direct air currents to the point of combustion, in combination with means for conducting oil to said hole in said floorbottom.

In witness whereof, I hereby set myhand this 6th day of May, A. D. 1911, at Seattle, county of King and State of Washington.
